Method for enhancing signal strength in mobile communication device

Abstract

A signal-strength enhancing structure for use in a mobile communication device, includes a mobile casing having an accommodation plate for receiving the mobile communication device thereon and a lateral portion extending outwardly from a periphery confining the accommodation plate to enclose the mobile communication device at least partially once placed on the accommodation plate; and a metal element connected to the mobile communication device via a gap-coupled device.

What is claimed is: 
     
       1. A signal-strength enhancing structure adapted to be implemented together with a mobile communication device, comprising:
 a mobile casing including an accommodation plate for receiving the mobile communication device thereon and a lateral portion extending outwardly from a periphery confining said accommodation plate so as to enclose the mobile communication device at least partially once said mobile communication device is placed on said accommodation plate; and 
 at least one metal element connected to said mobile communication device via a gap-coupled means; 
 wherein said accommodation plate of said mobile casing is further formed with a slide groove and an exposure opening, the signal-strength enhancing structure further comprises a pull strip mounted slidably in said slide groove so as to be extendible outwardly from and retractable into said accommodation plate, said pull strip has an inner side surface facing the mobile communication device and an outer side surface opposite to said inner side surface, said metal element is mounted on one of said inner and outer side surfaces of said pull strip, thereby movable together with said pull strip with respect to said accommodation plate, and said lateral portion of said accommodation plate is formed with a lateral opening for exposing a portion of the mobile communication device. 
 
     
     
       2. The signal-strength enhancing structure according to  claim 1 , wherein said metal element is mounted on said inner side surface of said pull strip. 
     
     
       3. The signal-strength enhancing structure according to  claim 1 , wherein said metal element is mounted on said outer side surface of said pull strip. 
     
     
       4. The signal-strength enhancing structure according to  claim 1 , wherein said metal element is connected to said inner side surface of said pull strip.
